# Assessing the Association Between Respiratory Symptoms and Nicotine and Cannabis Use Through Traditional and E-Product Devices in the U.S

## TL;DR

This study found that smoking cigarettes or cannabis is linked to respiratory issues, but vaping nicotine or cannabis is not.

## Contribution

The study provides new evidence on the differential respiratory risks of combustible versus e-product nicotine and cannabis use.

## Key findings

- Cigarette and cannabis smoking were associated with higher odds of respiratory impairment.
- Vaping nicotine or cannabis was not linked to respiratory impairment.
- Dual use of combustible cigarettes and cannabis had the strongest association with respiratory issues.

## Abstract

The aim of this study was to assess the association between past 30-day cigarette smoking, nicotine use with an e-product device (e.g., vape), cannabis smoking, cannabis use with an e-product device, and other forms of cannabis use and past-year respiratory symptoms in a nationally representative sample of people aged ≥12 years in the U.S. during 2021.

Data from Wave 6 (2021) of the Population Assessment of Tobacco and Health Study, a national probability sample of adolescents (aged 12–17 years; n=5,652) and adults (aged ≥18 years; n=30,516), were used. Logistic regression was used to assess the association of past 30-day cigarette smoking, nicotine use with an e-product, cannabis smoking, cannabis use with an e-product, and other forms of cannabis use with past-year respiratory symptoms (a past-year respiratory symptom index was constructed and ranged from 0 to 9; an index of 2+ was flagged as having functionally important respiratory impairment).

The odds of a past-year respiratory index score of 2+ was greater among respondents who indicated either past 30-day cigarette or cannabis smoking than among respondents who did not use any nicotine or cannabis during the past 30 days. Past 30-day nicotine and cannabis use with an e-product device was not associated with a respiratory symptom index of 2+. The combination of past 30-day cigarette smoking and cannabis smoking had one of the strongest associations with experiencing a respiratory index score of 2+ among dual users of nicotine and cannabis.

Past 30-day cigarette smoking and cannabis smoking were associated with higher odds of functionally important respiratory impairment. In addition, this study provides robust evidence regarding the potential respiratory harms of single or dual nicotine and cannabis smoking as it relates to respiratory health.

•Cigarette and cannabis smoking is associated with respiratory impairment.•Only vaping nicotine or cannabis was not associated with respiratory impairment.•Cessation services should be tailored for nicotine and cannabis use that involves combustibles.

Cigarette and cannabis smoking is associated with respiratory impairment.

Only vaping nicotine or cannabis was not associated with respiratory impairment.

Cessation services should be tailored for nicotine and cannabis use that involves combustibles.
